text: A pitch drop experiment was begun in the same year as the Queensland experiment at the University of St. Andrews. No evidence has emerged of any contact between Parnell and the instigator or instigators of the St. Andrews experiment. The pitch in the St. Andrews experiment flows in a largely steady, but extremely slow, stream. At some stage (likely in 1984) St. Andrews professor John Allen modified the St. Andrews experiment to bring its setup closer to that of the University of Queensland experiment.
